COMBINED TIE AND SUPPORT FORBARS.

Specification of Letters Patent.

Patented m. e, 1914;.

Application filed May 12, 1913. Serial No. 766,989.

To all whom it may concern Be it known that 1, JOHN THOMAS GRA- VEN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Combined Ties and Supports for Bars, of which the following is a specification. a

The object of the present invention resides in the provision of an improved combined tying and supporting device for reinforcing bars or rods arranged in crossed relation, such as bars or rods used to form cantaliver heads and those used in slabs or in any reinforced concrete construction in which the reinforcing bars or rods are to be supported in crossed relation above the forms or falsework. i

A further object of the present invention is to provide an improved combined tying and supporting device for reinforcing bars or rods that can be quickly and easily set in place after the bars or rods have been placed in their relative positions and will not only tie the bars or rods together in an effective manner without the use of wires or the like, but will, also, support the bars or rods at the proper distance above the forms or false,

work and, furthermore, one that is simple in construction and inexpensive to manufacture.

Further, the present invention consists of the novel features of construction and arrangement of parts hereinafter more fully described and pointed outin the claim.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation of a cbmbined tie and support for the bars or rods used in cantaliver heads; Figs. 2 and 3 are end and plan views, respectively, of same; Fig. 4 is a side elevation of a combined tie and support for the bars or rods used in the slabs; Figs. 5 and 6 are end and plan views, respectively, of same; Fig. 7 is a perspective view, on an enlarged scale, of the combined tie and support for the bars or rods used in the heads; Fig. 8 is a perspective view, on an enlarged scale, of the combined tie and support for the bars or rods used in the slabs; Fig. 9 is a perspective view, on an enlarged scale, of an alternate form of the combined tie and support; Fig. 10 is a plan view of the pattern from which the combined tie and support is formed; and

Fig. 11 is a plan view of the piece that is stamped from the pattern depicted in Fi 10, showing same perforated to be riveted to a bucket to be used as a bail lug.

Each combined tying and supporting device i is formed of sheet metal, which is preferably galvanized, though, of course, may be "formed of other suitable material. A blank 5 having preferably a rectangular configuration is stamped or out from the sheet metal, and has a piece 6 stamped or cut therefrom, leaving a slot 7 in one side thereof, which slot terminates in a central opening 8, which is preferably elongated and is somewhat elliptical in shape with its major aXis extending at substantially a right-angle to the axis of the slot 7, the side 9 directly opposite the slot 7being relatively narrow and connecting the-cnd portions of the blank, as clearly shown in Fig. 13. The blank is then bent into an inverted Uwshaped configuration by bending the narrow side 9 on the axis of the slot 7, so that the end portions of the blank diverge down: wardly from the bend in the side 9 and the ends 1001f the opening 8 register in horizontal alinement below the level of the bend inthe side 9. Bythis arrangement, the ends 10 of the opening 8 form seats for the lower bar or red 3, whilethe upper bar or rod 3 that rests upon and crosses the latter extends underneath the bcnd in the side 9, which serves the purpose of a tie for holding said bars or rods together.

In practice, after the lower bars or rods 3 have been laid approximately in position and the upper bars or rods 3 have been laid in position across the former, the combined ties and supports 1; are placed in position at the points where the upper bars or rods cross the lower bars or rods, so that said devices 4 stand in an upright position upon the forms or falsework, the lower bars or rods lying in the ends 10 of the openings 8 in said devices, and the sides 9 of said devices extending over the upper bars or rods, whereby said devices support said bars or rods at the proper distance above the forms or falsework and tie same together.

One great advantage arising from the use ofthese combined tying and supporting devices 4: is that same can be quickly and easily set in place after the bars or rods have been laid in their relative positions, and as no time is required for wiring the bars or rods together as is usually done, a

great amount of time is saved by the use toward the lower bar or rod and at the same time the ends of the device are moved downwardly underneath the latter until the device stands in an upright position with the lower bar or rod resting in the ends 10 of the opening 8 and the side 9 extending over the upper bar or rod, as hereinabove clescribed. ln addition to the time saved by the use of these combined tying and supporting devices, a saving in the cost of the construction is also derived from their use because of the low cost at which said devices can be manufactured.

It will be evident that the weight of the bars or rods upon a device 4L tends to make the lower ends of the latter spread apart,

but tendency of the lower ends of the device to spread apart causes the side 9 to draw the bars or rods closely together, with the result of tying the bars or rods together and holding same securely in place.

If desired, each end of the device may be arched as at 14, as depicted in Fig. 9, so that only the lower corners of the device rest upon the forms or .falsework, or the ends of the device may have notches or teeth or the like (not shown) formed therein to prevent same from slipping out of place on the forms I or falsework.

The piece 6, which is stamped or cut from the blank 5,'may be perforated to be used as a bail lug to be riveted or otherwise secured to a bucket or the like (not shown).

I I claim: 7

A support for rods or the like which are I arranged in right angular superimposed r elation, consisting of an integral member of inverted U-shaped formation having a rigid connecting end for the legs of the U-member, the legs of said member at the upper ends thereof being reduced in width and formed with concave seats at the bases of the reduced portions, the distance between the outside faces of the seats and the inner edge of the end of said member which connects the legs of the member being substantially equal to the combined thicknesses of the two superimposed rods, the inner end edge of the connecting end of the member beingfor seating engagement on the upper face of the uppermost rod, the legs directly adjacent to said connecting end being spaced at equal distances apart whereby the memher may be moved downwardly with said 1 JOHN THOMAS CRAVEN.
